Description of problem or question:
I am trying to re-encode a video. Handbrake is unable to see the subtitles contained in the source video. All I see is closed captions.
On one of my other machines, a chromebox running on Lubuntu 15.04 and handbrake 0.10.5 is able to detect subtitles.

Steps to reproduce the problem (If Applicable):
Simply setup an encode operation. I open up the file, load my preset and when I decide to add the subtitles I want from the source video file, I can only add CC and nothing else. On my Windows PC and Chromebox (which i obviously don't use for encoding) displays all available subtitles from the file.

One of the main reasons I put this machine up is to be able to do Handbrake video encoding, and it would be a shame i wouldn't be able to do that.
I checked the other thread a few threads below this one. The person had the same problem but all that was needed is to get the latest version and it seemed to have woirked for him/her. I am using the latest version. Is there something that has to be installed seperatly? maybe some codecs ?

So that is supposed to fix everything? I just need to uninstall my current Handbrake and then follow the instructions there? I will give it a try tomorrow. For now I am off to bed! I will let you know how it goes tomorrow. Thank you for your answer.

EDIT: The only way I managed to install handbrake is by sudo apt-get install handbrake, but that gives me the handbrake with the same problem. I guess the GTK is the toolkit which enables handbrake to function properly ?

I followed the instructions at the link Bradley pointed out. I added the rep, but when i wanted to install handbrake-gtk and handbrake-cli , it didn't work. Terminal said the package could not be found. After that, i used apt-get install handbrake and got me to the latest 1.0.7 version, where the subtitles aren't detected. Something isn't right :/ I mean, why isn't the handbrake-gtk package not found while i try to follow instructions?

Yes, but what do I do now? I am not a linux expert xD
How can i get to an older version ? I tried getting 0.9.5 which worked on my other machine but there i have a dependencies error (too old) when trying to install it on this machine.

E: The repository 'http://ppa.launchpad.net/stebbins/handbrake-releases/ubuntu artful Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

I'm pretty sure that's what happened cause I remember searching somewhere and finding the snapshots rep. Then I ran the commands and it worked I'm glad this worked out in the end!

I successfully encoded a video. However, I noticed that encoding stops when I close down the screen and turn it back on. It gets me to the login screen and when I log back in, all programs are closed. Besides that, I use caffeine to be 100% sure nothing logs out. Do you know a solution around this? I turn off my TV and turn it back on the encoding stops :/ Maybe I didn't have caffeine on when that happened.
EDIT: I just tried it again and it's ridiculous. I can't turn back on the TV until the whole thing is done. It just puts me to the login screen and the encoding stops (I base myself on my stock coolers loud noise (which I will change soon)).
